Most elements found in nature with the exception of the

Chemistry
1 answer:
Ira Lisetskai [31]3 years ago
8 0

The right answer is noble gases.

The noble gases, or rare gases, are the chemical elements of group 18 (formerly "group VIIIA" or even "group 0") of the periodic table. These are helium He, neon 10Ne, argon 18Ar, krypton 36Kr, xenon 54Xe and radon 86Rn, the latter being radioactive.

This property means that they can not bind with other atoms to form molecules or lose electrons to transform into ions, hence their name noble or inert gases (they are not very active and do not do not mix). In nature, all elements "want" to become stable.

An inventor claims to have devised a closed cyclic engine which exchanges heat with cold and hot reservoirs at 25 and 350 ◦C, re
kati45 [8]

Explanation:

The given data is as follows.

T_{c} = 25^{o}C,  T_{h} = 350^{o}C

Work produced per kJ of heat extracted from hot reservoir = 0.45 kJ = Efficiency

If the device is Carnot cycle then its efficiency will be maximum and its value will be equal to [1 - (\frac{T_{c}}{T_{h}} )]

Using this relation we will calculate the efficiency as follows.

                 Efficiency = [1 - (\frac{T_{c}}{T_{h}} )]

                        = 1 - (\frac{25}{350})

                       = 0.928

Hence, it means that this type of device is possible and the claim is also believable.
